MAXQ1004-B01+

Product Overview

MAXQ1004-B01+ is a Maxim MAXQ1004 application-specific controller associated with Analog Devices / Maxim Integrated. The device is cataloged under application-specific microcontrollers because its processing and peripheral resources are optimized for a defined control task rather than general-purpose MCU use.

The parameters below are limited to information located for this exact part or its directly matching base device. Values not reliably exposed in public documentation—especially for customer-programmed TrueTouch, Broadcom and legacy controller variants—are intentionally not inferred from a neighboring suffix.

For MAXQ1004-B01+, security provisioning forms part of the component identity. Review the host command set, cryptographic functions, key-injection process, lifecycle state, nonvolatile-memory organization, supply sequencing and package connections. A blank secure controller, a differently provisioned unit or another ordering option may be electrically present yet unable to authenticate with the installed host. Migration therefore requires controlled provisioning and end-to-end challenge-response testing.

Key Features

• Full part number: MAXQ1004-B01+
• Manufacturer / historical brand: Analog Devices / Maxim Integrated
• Device type: Maxim MAXQ1004 application-specific controller
• 16-bit MAXQ pipelined CPU
• 1-Wire slave and SPI interfaces
• AES engine and random-number generator
• Integrated 10-bit delta-sigma ADC and temperature sensor
• Designed for authentication in battery-powered equipment

Applications

• Secure authentication and protected embedded control
• Battery-powered or connected products requiring the matching security architecture
• Legacy design maintenance with preserved provisioning data

Application suitability should be confirmed against the original system requirements, including interface role, firmware revision, environmental range, package assembly process and any programmed or calibrated data. These examples describe realistic uses of the researched device family; they do not imply that every ordering suffix includes every optional peripheral or qualification grade.

Quality & Sourcing

Antrex Electronics can support sourcing review for MAXQ1004-B01+, including verification of the complete ordering suffix, package, date code, packaging form and visible marking. Buyers should state the required quantity and whether blank, factory-programmed or customer-programmed material is acceptable. For programmable, secure or touch-controller devices, the firmware image, security provisioning state and customer option code can be as important as the silicon itself; Antrex Electronics does not assume that blank stock will reproduce an installed part. For obsolete or long-stored material, photos, label review, traceability checks, lead or ball inspection, solderability assessment and third-party electrical or X-ray testing can be arranged when project risk warrants them. Availability, date code and test scope remain subject to quotation and inspection.
